11kV 33kV Combined Metering Unit Output Transformer

1.Application:

This combined instrument transformer is for use with electrical measuring instruments and electrical protective devices. It consists of a current transformer and a voltage transformer in the same case.

Our combined instrument transformer is especially suitable for HV metering, to do so, two voltage transformers shall be connected in V type, while two current transformers connect serially to phase A and C. The instrument transformer can be fixed on the post of transmitting line. The secondary output connects directly to an independent HV metering box. Users can choose certain connection in accordance with different conditions.

1).Rated Voltage (kV): up to 35kV

 2).Rated Primary Current: up to 1000A or custom specified

 3).Rated Secondary Current: 5A

 4).Accuracy Class: up to 0.2s for metering; up to 0.2, 0.5 for protection

 5).Rated Frequency: 50Hz (60Hz on request)

 6).Installation: outdoor

 7).Insulation Material: epoxy resin and silicon jel

 8).Winding: high quality enameled copper wire

* Except for the technical parameters list above, we can design as per clients’ requirements.

1).A metering unit consisting of one CT and one VT

 2).With small volume and good performance

 3).Multi-taps at the secondary windings, which makes different current transformation ratio for the current exchange of customers while power consumption increasing

4. Manufacturing Standard: IEC60044-3:2002, GB17201-2007

5.Technical Parameters for JLSH(G)W-10 II Metering Devices
